Hello list,

I have written a function which prototype is:

  FILE * getContent (void  * objetc, char  * code);

This function a FILE * to a temporary file it fill with user data, and copy
in "code" (with strcpy) some string

I warpedd this function with Swig, but when I call it from a Ruby script, I
have two problems:

1- The class of the function output in Ruby is <SWIG::TYPE_p_FILE>,  what is
this class? I looked for it in the net by without results, Hows can I
recover the data from my temporary file with this?

2- when I call this function from a C program, the variable code will
contain a string value that the function copy to it from an other variable
in internal. and with a C program, the content of the variable code is
updated very well. But when I call the wrapped function from a Ruby script,
the argument code stays empty (empty string "")? How have to give this
argument in such way that it will be modified?

thank you
